I’ve raised this with Nick but just wondered if anybody else has having similar issues.
I updated WP to 4.0.1 and existing sites where I had used Page Builder up to 2.0 now have an issue when I add or amend a Page Visual Editor Widget and add an image via Add Media it doesn’t appear. I can pick the image and confirm it but it doesn’t appear in the Visual Widget. But when I look at the Visual Style the image is there!
I have just tried this on a website and it worked fine with WP 4.0 and PB 2.0, upgrade WP to 4.0.1 and it stops working.
